Skywatchers at high latitudes could be in for a spectacular treat of northern lights, the aurora borealis, Tuesday and Wednesday: After a relatively quiet stretch, it appears the sun is ramping up its activity. The sun's surface erupted early Sunday, blasting tons of plasma (ionized atoms) into space. These atoms are headed toward Earth and could create a stunning light show in the process.
The solar eruption, called a coronal mass ejection, was spotted by NASA's Solar Dynamics Observatory , which captures high-definition views of the sun at a variety of wavelengths. SDO was launched in February and peers deep into the layers of the sun, investigating the mysteries of its inner workings.
